Plants Really Do 'Scream'. We've Simply Never Heard It Until Now.

“…The sounds plants emit are like popping or clicking noises in a frequency far too high-pitched for humans to make out, detectable within a radius of over a meter (3.3 feet). Unstressed plants don't make much noise at all; they just hang out, quietly doing their plant thing.…”

It seems like Roald Dahl may have been onto something after all: if you hurt a plant, it screams.

Yes I have been hearing of this. Surprising that there has been no research into using these sounds to fine tune watering and other interventions in agriculture

It was all interesting until they started "We don't know how these sounds are produced"... That's the least they should evaluate before posting bold claims.
More of click bait than something substantial, such theories keep coming up from time to time, hardly any sustain.

@krack your scepticism is ok. But scientific research mostly is reported at stages where there is discovery of an established phenomenon or fact. The sounds produced by plants when hurt have been recorded. That’s a fact even if it may not be exciting to some.
Here is the paper: https://www.cell.com/cell/fulltext/S0092-8674(23)00262-3
The next stage of the research is mentioned….
How they make these sounds (is it similar to humans cracking knuckles? Is one hypothesis)
The more interesting questions are if plants are making sounds when hurt, then who is listening?… how? Evolution of any ability or trait always has a purpose.

I'm sure the sceptics would be "pure" vegetarians.

It is now well established that plants to communicate though a vast fungal network- mycellium network.

Interplant signalling via CMNs is a recently discovered process that has wide implications for ecology, evolution and sustainable agriculture. We need to increase the types of experiments to consider more natural systems, including those with diverse assemblages of plants, fungi and insect herbivores.

That's not a simple Skepticism, Basically Sound is a Vibration, Vibration enough to move Reasonable quantity of air to make a perceptible difference to someone's ear or recording device.
Now, most of the Chemical Reactions emit a form of light or sound or radiation which may or may not be perceptible or recordable. In fact, the famous crackers sound is a nothing but a perceptible sound emitted from a chemical reaction.

I remember reading organic sono chemistry in which the ultrasonic frequencies are used to alter the chemical properties of the compounds or piezoelectric properties, so that a desirable chemical result is achieved. Vice versa organic reactions producing ultrasonic frequencies is is well documented.

A dying tree, or a tree in distress is nothing but a tree undergoing a series of organic chemical reactions or in fact a cascade of organic chemical reactions which will eventually end up with the death or damage of a tree. The series of chemical reactions are mostly same in any dying tree so it may match with the ultrasonic characteristics every time. To quantify those ultrasonic sounds emitted in a cascade of similar chemical reactions and calling it a Scream is a bit of stretch in my opinion. Purely because scream is generally attributed to a common audible emotion. Anyways, its more sensational than substantial.

BTW, thanks for the article share that was an exercise to Grey matter, but I couldn't agree much with the conclusions.

How can we be sure that plants are screaming and not farting

If someone cut me I could fart instead of scream I suppose

Let's not forget Jagadish Chandra Bose's invaluable contribution to the botany. one of the most elite scientists from India on par with Srinivasa Ramanujam IMHO. NASA even named their x-ray observatory after him...

Jagdish Chandra Bose & plant neurobiology

When Jagdish Chandra Bose, a renowned physicist, devoted himself entirely to research in the field of plant physiology post his superannuation at Presidency University, Kolkata, India (earlier known as Presidency College, Calcutta), it came as a surprise ...

All life on earth has evolved from a single cell that could replicate itself. No wonder you find few things similar in all life forms like mitochondira. Yes, plants have mitochondria, which are organelles found in the cells of most eukaryotes, including plants, animals, and fungi. Mitochondria are responsible for integrating sugar produced in the cell to generate energy, usually during the day through photosynthesis. At night, plants continue to make energy through cellular respiration. All life is a sequence of A-G and C-T pairs which define the genetic code and decides if we are going to be a mouse, plant or a human being. All have persisted since roughly 3.7 billion to 3.5 billion years ago during the Archean Eon (4 billion to 2.5 billion years ago), products of the great evolutionary process with its identical molecular biological bases adenine, guanine, cytosine and thiamine. Based on commonality or differences all life was classified by Carl Linnaeus in 1753, a Swedish biologist named Carl Linnaeus (also known as Carl von Linné) proposed a universal system for classifying and naming animals and plants. Scientists still use this Linnean system to classify living things.

agree, but there are instances (aka. 'leaps') in evolution which cannot be explained by today's science (Darvanian evolution) except 'the hand of God'. topic for another day i guess

mitochindria was an output of bacterial evolution and scientists think there was no way it could happen naturally (because of differences in enery levels). i could be very wrong but let me hunt for my sources. nevertheless, great conversation @mbhangui

When they cry, it is so fragrant. The grass smell at the blades of the lawn mower is an example. Also the insectivorous plants were said to communicate with their trapped preys to the extent of saying sorry it seems. In Yercaud botannical garden, a guy told me.

Absolutely! The olfactory sensations that are evoked when a part of a plant is cut is striking. Specially the leaves and fruits.
While many are fragrant there are some like this: https://en.wikipedia.org/wiki/Amorphophallus_titanum
Objective Measurements of the smells from plants would be through chemical qualitative and quantitative analysis I guess.

Actually, no; it is named after S. Chandrasekhar - the Nobel prize laureate.

The concept of Darwinian evolution is just a theory and like all theories, it has its flaws and gaps just like religious dogma about evolution. I don't think science in its present form can conclusively explain what happened over billions of years so all we have are theories (some are even rooted in conspiracy) and if we don't like them - there's always religion!

Very true since it is almost impossible to predict what exactly happened thousands of years ago and how the dinosaurs got extinct.
Evolution of humans is also a moot point. Judging by the consistent omnipresent digging in cities, one gets a feeling that human kind may have evolved from the rodent family.
